anderson double hung window counter balance

A contractor from Cape May says:
First thank you for your help with Anderson balance part # couple weeks back. Also how to video you have on how to replace is spot on. A+++

Today I have two Anderson double hungs.

First one measure approximately 36x61

Second one measures approximately 40x61

It was our pleasure! For these balances, I recommend our 24-1033 and 24-1231, for the 10#31 and 12#31, respectively.
